 wherein a pitch of the plurality of lenses is defined in a second direction crossing the first direction. 
 
     
     
       9. The display device of  claim 8 ,
 wherein each of the plurality of fixing pins is disposed between lenses neighboring to each other among the plurality of lenses, in the first mode. 
 
     
     
       10. The display device of  claim 8 ,
 wherein the display panel includes a plurality of pixels each including an emission area, and the plurality of fixing pins do not overlap the emission area. 
 
     
     
       11. The display device of  claim 8 ,
 wherein the plurality of fixing pins include a transparent material. 
 
     
     
       12. The display device of  claim 1 ,
 wherein the resin includes a material that moves according to the magnetic field. 
 
     
     
       13. The display device of  claim 12 ,
 wherein the resin includes ZrO 2  or Fe 3 O 4 . 
 
     
     
       14. The display device of  claim 1 , further comprising:
 a connection part connected to the switchable lens layer; and 
 a winding part connected to the connection part, wherein the winding part unwinds the connection part when in the first mode, and winds the connection part when in the second mode. 
 
     
     
       15. A display device comprising:
 a display panel displaying a 3D image in a first mode and displaying a 2D image in a second mode; 
 a switchable lens layer disposed on the display panel; 
 a plurality of fixing pins disposed on the switchable lens layer; and 
 a resin supply part connected to the switchable lens layer and supplying the resin to the switchable lens layer, 
 wherein the switchable lens layer has a plurality of lenses in the first mode because the resin moves from the resin supply part to the switchable lens layer in the first mode, and the switchable lens layer has a flat shape in the second mode because the resin is stored in the resin supply part in the second mode, and 
 each of the plurality of fixing pins is disposed between lenses neighboring to each other among the plurality of lenses. 
 
     
     
       16. The display device of  claim 15 ,
